Abstract: EARTH BORING BIT WITH TEXTURED BEARING SURFACE            Abstract of the Disclosure A rolling cutter earth boring bit is provided with load bearing surfaces that provide small lubricant reservoirs between the bearing interfaces.  At least one of the bearing surfaces between the cutter and bearing pin is first ground, machined, etched or otherwise smoothed to an initial surface roughness of less than 20 Ra.  The surface is then roughened by shot peening or other surface roughening techniques, such as electric discharge machining, chemical etching or other standard methods of roughening a surface.  The desired rough-ness should have a value higher than about 20 Ra and less than about 80 Ra.  The roughening procedure is limited, generally with less than 50% of the surface area containing indentations.  The indentations provide reservoirs for lubricant and a receptacle for debris in the bearing area. The smooth portions of the bearing promote rotation of the cutter on the bearing pin.

Abstract: WAVE-OPERATED ELECTRICAL GENERATING SYSTEM     ABSTRACT       A system for converting the mechanical energy in the wave motion of a body of water into electrical energy.  A frame is fixed with respect to the wave motion of the water.  A flotation element is buoyantly supported by the water and constrained to follow only the vertical component of the wave motion.  The motion of the flotation element is transferred to an electrical generating device which includes a device for producing electromagnetic flux and electrical coils.  The motion of the flotation element causes relative motion between the flux-producing device and the elec-trical coils thereby generating an electromotive force.  A positioning subsystem is provided for moving the electrical generating device relative to the flotation element when the average depth of the body of water changes so as to maintain a symmetrical relative motion between the flux-producing device and the electrical coils.

Abstract: ABSTRACT        An oil spill recovery method and apparatus is disclosed.  The method of recovery involves the pumping of an oil/water mixture from a concentration area to the submerged portion of a vertically oriented cylinder, open at both ends, and the separation of the oil from the water in the cylinder.          Oil floats to and accumulates on the surface of the water in the cylinder and uncontaminated water flows out through the lower open end of the cylinder.  The apparatus includes a collection unit which defines the concentration area within three walls thereof, a recovery unit which follows the collection unit and mounts the cylinder therein, and a sub-merged pumping unit which carries an oil/water mixture from the concentration area in the collection unit to the cylinder in the recovery unit.  There is very little emulsification of the oil in the cylinder and hence there is very efficient separation of the oil from the water.

Abstract: Abstract A step-ladder is disclosed in which at least one of the two legs, connected by a pivot at their upper ends, comprises transverse members constitut-ing treads carried on uprights and spaced from each other in the longitudinal direction of the uprights, the transverse members forming steps located in a horizontal plane when the said legs are spread to the maximal extent and the ladder is standing upon a horizontal surface. The steps are connected to the uprights in such a manner as to pivot about axes running parallel with each other, and to links running parallel with the uprights.  The uprights and the links, when the legs are at their maximal distance apart, provide mutual support increasing the resistance to bending and limiting the extent to which the steps can pivot about their axes.  The steps have an overhang, beyond the sides of the uprights remote from the other leg, which, when stepped upon, produces a torque tending to bring the links  closer to the uprights. The depth of the steps, and the difference in height between two consecutive steps, is within the range commonly used for stairs.

Abstract: ABSTRACT OF THE DISCLOSURE           A novel cleaning and sanitizing composition for industrial and/or agricultural use is provided herein as well as a novel method for cleaning and/or sanitizing industrial and/or agricultural machinery.  The cleaning composition includes a solution of a cleaning agent and a suffi-cient amount of a gelling agent to provide a thixotropic gel, which can be sprayed onto a surface to be cleaned at a minimum pressure of 15 p.s.i. to deposit a film on the surface of at least 5 mils thickness on a vertical surface and to remain thereon with no slump for at least one-half hour.          Thus, the novel method includes spraying a thixotropic gel form of a cleaning agent at a pressure of at least 15 p.s.i. onto the surface to be cleaned to provide a film at least 5 mils thick, allowing the film to remain on the surface for a predetermined length of time, e.g., at least 10 minutes, and then rinsing off the composition and the material to be. cleaned from the surface to be clean with a high pressure water stream.          This provides an economical yet efficient composition and method for cleaning and/or sanitizing industrial and/or agricultural machinery.

Abstract: APPARATUS AND METHOD FOR QUALITATIVE AND QUANTITATIVE DETERMINATION OF IMMUNOLOGICAL REACTIONS                 Abstract of the Technical Disclosure An apparatus and a method are provided for qualitative and quantitative determinations of agglutination in immunore-active systems, and for determining the concentration of the immunocreactive components of such systems.  The apparatus comprises a carriage assembly having a plurality of spaced, axially-disposed compartments for receiving image cells which are uniquely designed for holding the biological fluid test specimen and the reagent therefor.  Means are provided for partially lifting each image cell successively out of its compartment and into an optical path.  A monochromatic light source directs beams of radiant energy through the reaction zone in each image cell and the light beams transmitted through the reaction zone are focused, by means of an imaging lens, on the surface of an image sensor such as a "Charge-Coupled Device."  The dark areas formed on the image sensor are measured electronically and also displayed on a display cathode ray tube.     The method of this invention comprises introducing the fluid biological test specimen and the reagent (e.g., latex spheres) into a reaction zone in the image cell, evenly mixing and incubating the mixture thereby forming agglutinated particles.  After transilluminating the reaction zone and imag-ing the light beams transmitted therethrough on the image sensor, the dark areas formed on the surface of the image sensor are measured, preferably electronically.                             -.alpha.-This procedure is repeated for a reference speciment and the total dark imaged area is compared with the total dark area obtained for the unknown specimen for qualitative determination.     In order to obtain the concentration of the immunore-active component in the unknown specimen, the foregoing procedure is repeated for at least two specimens with known antibody concentrations, one of which may be a negative control.          The concentration of the immunoreactive component of the un-known sample is then determined from the total dark imaged area thereof and the relationship between the total dark imaged areas of the known specimen and their respective concentrations.                             -b-

Abstract: TAPE MEASURE                              Abstract A gearless, open-faced, direct-drive, spring-rewound tape measure eliminates the need for a manual-rewind handle or gears to increase the spring tensioning force.  A spiral spring is retained within a spring-retaining disk which is revolvable about a hub attached to a cover.  A cover plate coupled through an input disk allows revolving of the spring-retaining disk to adjust the tension of a spring which is retained within a spring-retaining well of the spring-retaining disk.  Alterna-tively the hub may be attached to the cover plate and the spring tension adjusted by revolving the cover plate while the spring-retaining disk remains stationary.  In ordinary use, the cover plate is restricted from revolving by compression lock rings which sandwich the cover plate.
